Questions people ask while picking a pattern or planning a slab

Updated November 10, 2026

Is this site a contractor?

No. DFW Stone & Concrete is a quoting and scheduling service. The pages help you choose a pattern, finish, stone or slab spec; when you ask for a quote, your request goes to one independent, insured North Texas contractor who prices the job and does the work.

What do you quote?

Stamped, colored, stained and exposed-aggregate concrete, flagstone and natural stone, pool decks and coping, the hardscape for outdoor kitchens and fire features, and shop, barn, RV, boat and garage slabs, in eight DFW counties.

Do you publish prices?

No. A price without the pattern, the stone, the slab spec and the lot is a guess. We publish the spec and the sources, and the quote carries the number.

What is on the quote?

The pattern or stone, the color method and sealer, and under them the thickness, steel, base, joints and any vapor retarder or edge detail, each on its own line, with dates for the pour, the seal and the first use.

Which counties do you cover?

Dallas, Tarrant, Collin, Denton, Rockwall, Ellis, Johnson and Parker. Each county page lists who permits work outside city limits, where the parcel records are and what the ground does, with a source for each fact.

Who does the work if I request a quote?

An independent, insured North Texas contractor. The certificate of insurance, the written quote and lien releases come from that contractor.

Can a stamped pattern hide the control joints?

Often, if the layout is planned so the saw cut or tooled joint falls in a grout line. Ashlar, plank and brick patterns take it well; cobblestone and fieldstone less so. Ask for the joint layout on the sketch.

Is stamped concrete slippery?

Sealed, textured concrete can be slick when wet, especially a high-gloss sealer. A grit additive in the sealer is the usual fix and should be on the quote for a pool deck.

Can you stamp an existing patio?

Not the slab itself. A sound slab can sometimes take a stamped overlay; otherwise the choices are stain, dye or a new pour. We look first.

How many patterns can go on one patio?

Two is common: a field pattern and a border in a second texture or a plain band. More than that gets busy and adds layout time at the edges.

Will the color match the sample exactly?

Close, not exact. Integral color shifts with the mix and water; acid stain is different on every slab by nature. Approve a sample on your concrete, not a chip.

Does colored concrete fade?

Integral pigment and color hardener are iron-oxide and hold up in sun. Acid stain is fade-resistant. Dyes fade or darken outdoors and are not used on exterior work here.

Can an old patio be colored?

Yes, with an acid or water-based stain after cleaning and testing. Integral color and hardener are only for new pours.

Is two-tone color possible?

Yes. The usual route is a base color plus a darker release on stamped work, or a stain applied in layers on a cured slab.

Is exposed aggregate rough on bare feet?

Smaller, rounded pebble exposed shallow is comfortable; large crushed stone exposed deep is not. For a pool surround ask for a small rounded aggregate and shallow exposure.

Can I choose the stone?

With a seeded finish, yes. With a monolithic mix you choose from what the ready-mix plant batches.

Which broom finish for a driveway?

Medium, pulled across the slope. Coarse is for ramps and steep approaches.

Does exposed aggregate need sealing?

It is not required but it is usual; it keeps the stone from loosening and keeps the color.

Dry-laid or mortared for a patio?

Dry-laid if you want flexibility on clay and the ability to relay a stone; mortared if you want a solid, even surface, especially over an existing slab or at a door.

Will weeds grow in the joints?

Polymeric sand sets when wetted and limits weeds in dry-laid joints. Mortar or grout joints do not grow weeds but can crack with slab movement.

How thick should flagstone be?

One to three inches for pavers; thicker stone is steadier on a dry-laid base, thinner is fine in mortar.

Can flagstone go over my existing patio?

Yes, mortar-set, if the slab is sound and drains. That is one of the common uses of the mortared method.

Which pool deck finish stays coolest?

Light colors in any finish. A pale integral color or hardener with a matte sealer stays cooler than a dark stamped slab.

Is stamped concrete safe around a pool?

With a slip additive in a matte or satin sealer, yes. Without one, a sealed stamp can be slick when wet.

Can you replace a pool deck without touching the pool?

Usually. The deck is saw-cut at the coping or the beam and re-poured; the coping and the beam are the pool builder's domain.

Who sets the coping?

Either the pool builder or the deck crew, depending on the sequence. The quote should say which and when.

Do you install the grill and countertops?

No. We build the pad, base and walls; the appliance, gas, electrical and countertop trades do their part. We coordinate the sleeves and the sequence.

How thick is a fireplace pad?

Thicker than a patio. One manufacturer's manual calls for an 8-inch reinforced pad over 6 inches of compacted stone. Follow the manual for your unit.

Can the fire pit sit on the existing patio?

A light gas kit sometimes can if the slab is sound and the gas line can be run; a masonry fireplace needs its own pad. We check the slab first.

Does an outdoor kitchen need a permit?

Often, for the gas and electrical, and sometimes as an accessory structure. Frisco, for example, requires a building permit for all accessory structures. Verify with your city.

How thick should a shop slab be?

Four inches nominal for storage and light vehicles, six where heavy equipment parks, with the edge detail from the building drawing. Spend first on the pad.

Do I need a vapor barrier under a shop?

If the inside will be conditioned, floored or used to store things that cannot get damp, yes: at least 6 mil by code, 10 to 15 mil Class A in practice, directly under the slab.

Who sets the anchor bolts?

Usually the concrete crew, to the building supplier's bolt plan, before the pour. The quote should say so and name the plan.

Does the county permit a shop slab outside city limits?

It depends on the county. Collin and Ellis list barns and shops among projects that need a development permit; Tarrant and Parker issue no building permits; others permit development generally. See the county pages.

How thick should an RV pad be?

Five to six inches with thickened edges and rebar on chairs. Four inches is a car spec.

Can the pad be gravel instead?

It can, but it is not what we quote; a gravel pad ruts under a parked coach on clay and is a different trade.

Should the pad slope?

Yes, slightly, away from the house and the garage, so water does not sit under a parked vehicle.

Do I need a permit for an RV pad?

The approach at the street almost always; the pad itself depends on the city and the HOA. Verify both before the layout is set.
